2 Claims.

My invention aims to provide improvements in buttons of the sew-on type.

In the drawing which illustrates a preferred embodiment of my invention: Figure 1 is a plan view of an imitation woven button;

Fig. 2 is a side elevation of the button shown in Fig. 1;

Fig. 3 is a back view of the button shown in Fig. 1;

Fig. 4 is an enlarged section taken on the line Y 4--4 of Fig. 3;

Fig. 5 is a section similar to Fig. 4 but showing the thread-receiving aperture and adjacent wall only partially completed; and

Fig. 6 is a section taken on the line G-B'of Fig. 3.

My invention is particularly, though not exclusively, useful in connection with buttons having metal backs from which are pressed relatively long, slender boss portions shaped to provide sewon thongs which may be sewed to an article of wearing apparel or the like by machine. The particular button illustrated is a two-piece sheet metal imitation woven leather button.

Referring now to the specific button selected for illustration by the annexed drawing, I have shown a construction which includes a hollow metal cap l having a series of line-like depressions 2 formed in theupper face thereof to present a predetermined design such, for instance, as that which would be presented by a woven leather button. The button also includes a back plate 3 the central portion of which is pressed out to provide a relatively long slender boss of substantially 35 uniform cross-section throughout its length, as clearly illustrated in Figs. 2 and 3. This boss 4 has a thread-receiving hole extending through it at right angles to the axis of the boss and the metal of the thong which is pressed out to provide the hole is so arranged that it provides a substantially smooth continuous wall 6 at least adjacent to the free end of the boss 4, as clearly illustrated in Figs. 4 and 6.

One practical method of forming the threadreceiving hole and the thread-engaging wall B in the boss 4 is substantially as follows. After the boss 4 has been pressed from the back plate 3 a suitable sharp pointed tool is kforced through one side of the boss 4, thereby forming the threadreceiving hole 5 in that side, and at the same time the metal forced out to form the hole is pressed into the hollow boss 4 in substantially the manner illustrated by Fig. 5. Thereafter a suitable implement is forced through the opposite side wall 55 of the boss 4 to complete the thread-receiving t (Cl. 2li-9S) opening 5 and the thread-engaging wall 6. During this last operation the inwardly pressed wall portion engages the wall portion rst formed and a portion of it is depressed where the two portions overlap (Fig. 4) so that the two surfaces will form a smooth substantially continuous wall for engagement with the thread. p

My improved button is particularly desirable because it permits the use of a metal button having a relatively long thong provided with a thread-receiving aperture having a wall extending entirely through the thickness of the thong and presenting a smooth continuous surface for engagement by the sewing thread so that the thread will not become cut by engagement with the metal during use. Furthermore, my invention includes the idea of providing a simple, twopiece button which when properly finished presents the appearance of a woven leather button both as to marking and color.

WhileI have illustrated and described a preferred embodiment of my invention, I do not Wish to be limited thereby, because the scope of my invention is best dened by the following claims.

I claim:

1. A sew-on button having a metallic back plate, a one-piece boss extending from said back plate and having a thread-receiving hole therethrough adjacent to the free end and a substantially continuous wall integral with the boss extending the entire length of the hole at that side adjacent to the free end of the boss, and said wall being formed by overlapping portions constructed and arranged to provide a substantially continuous smooth surface with one of the overlapping portions offset relative to and underlying the other portion.

2. A sew-on button having a metallic back plate, a one-piece hollow boss portion extending from said back plate, a thread-receiving hole extending through said boss adjacent to the free end at right angles to the axis of the boss'and a wall portion integral with said boss and extending from one side of said boss toward the other at the periphery of said hole and another wall portion integral with said boss and extending toward the first-mentioned wall portion from the opposite side of said boss whereby said wall portions provide the only thread-engaging means adjacent to said hole and said walls engaging each other and overlapping inside the base to form a smooth thread-engaging portion extending entirely through the boss at the periphery of the threadreceiving hole.
